**7. Final conclusions**

This chapter was based on our experience in the pathology of the carotid arteries and barror‐ eceptor as well as what exists in the international literature. The importance of knowing the biological phenomena that produces the formation of carotid atheromatous plaque is clearly emphasized. We also mentioned different plaque types (stable, unstable and calcified) and its correlation with diagnostic techniques. Concepts approached in the chapter offer the reader elements to enhance decision making in patients suffering carotid atheromatous disease. Additionally we emphasized the need to report on the origin and hemodynamic behavior of the carotid dolichoarteriopathies. Finally, we have highlighted the functions and the various pathological processes that can be observed in the carotid glomus.
